Are the CKM anomalies induced by vector-like quarks? Limits from flavor changing and Standard Model precision tests
Abstract Recent high precision determinations of V us and V ud indicate towards anomalies in the first row of the CKM matrix. Namely, determination of V ud from beta decays and of V us from kaon decays imply a violation of first row unitarity at about 3σ level. Moreover, there is tension between det...
